Moreover, the viscosity in a table | surface is the value measured by the following method.
<Measurement method of viscosity>
After preparing the hair treatment agent according to each example and each comparative example and allowing it to stand for 3 days to stabilize, RB80 type viscosity which is an R type viscometer manufactured by Toki Sangyo Co., Ltd. at 25 ° C. Using a total VISCOMETER, the viscosity value (mPa · s) was measured with a No. 3 rotor or a No. 4 rotor for 1 minute under a measurement condition of 12 rpm / min.
In addition, when a viscosity range is 1000-5000 mPa * s, it can obtain | require on the conditions of 12 rpm / min using a No. 3 rotor. When the viscosity range is 5000 to 50000 mPa · s, it can be obtained under the condition of 12 rpm / min using a No. 4 rotor.

[3] Performance evaluation (Elongation to hair when wet, fingering when dry, and relaxation effect on the crust of hair tips)
The following evaluation methods and evaluation criteria were used to evaluate the effects of stretching on hair when wet, following the fingers when dry, and reducing the roughness of the hair tips.

(3-1) Elongation to hair when wet 10 g of chemically treated hair sample prepared as in [1] above is washed with water and washed with a hair cleaner (“Promaster Color Care LX Stylish Line” manufactured by Hoyu Corporation). And then washed again with water. Next, 3 g of the hair treatment agents of Examples 1 to 26 and Comparative Examples 1 to 7 were uniformly applied to the entire chemically treated hair sample, and the elongation to the hair when wet was evaluated.
Regarding this evaluation item, 20 panelists evaluated the hair for evaluation treated according to the above-mentioned procedure by selecting “good” or “not good”, and among 20 people, “good”. The case where there are 20 to 17 panelists who responded is the evaluation point 5, the case of 16 to 13 is the evaluation point 4, the case of 12 to 9 is the evaluation point 3, and the case of 8 to 5 is the evaluation The case where the number of points was 2 or 4 or less was set as the evaluation point 1. The evaluation results are shown in each table.

(3-2) As per finger at the time of drying After washing 10 g of the chemically treated hair sample prepared as in [1] above and washing with a hair cleanser (“Promaster Color Care LX Stylish Line” manufactured by Hoyu Co., Ltd.) And washed again with water. Next, 3 g of the hair treatment agents of Examples 1 to 26 and Comparative Examples 1 to 7 were uniformly applied to the entire chemically treated hair sample, then washed with water, dried with a towel, dried with a dryer, and evaluated for fingering during drying. Went.
Regarding this evaluation item, 20 panelists evaluated the hair for evaluation treated according to the above-mentioned procedure by selecting “good” or “not good”, and among 20 people, “good”. The case where there are 20 to 17 panelists who responded is the evaluation point 5, the case of 16 to 13 is the evaluation point 4, the case of 12 to 9 is the evaluation point 3, and the case of 8 to 5 is the evaluation The case where the number of points was 2 or 4 or less was set as the evaluation point 1. The evaluation results are shown in each table.

(3-3) Relieving effect of hairiness of the hair tip 10 g of the chemically treated hair sample prepared as described in [1] above is washed with water and washed with a hair cleanser (“Promaster Color Care LX Stylish Line” manufactured by Hoyu Corporation). And then washed again with water. Next, 3 g of the hair treatment agents of Examples 1 to 26 and Comparative Examples 1 to 7 were uniformly applied to the entire chemically treated hair sample, then washed with water, dried with a towel, and then dried with a dryer to reduce the crustiness of the hair tips. Was evaluated.
The term “crisp of hair” as used herein refers to a state in which the hair has a dry texture due to insufficient moisture, feels firm, spreads, and the hair is not well organized.
Regarding this evaluation item, 20 panelists evaluated the hair for evaluation treated according to the above-mentioned procedure by selecting “good” or “not good”, and among 20 people, “good”. The case where there are 20 to 17 panelists who responded is the evaluation point 5, the case of 16 to 13 is the evaluation point 4, the case of 12 to 9 is the evaluation point 3, and the case of 8 to 5 is the evaluation The case where the number of points was 2 or 4 or less was set as the evaluation point 1. The evaluation results are shown in each table.

[4] Effects of Examples According to Tables 1 to 4, the evaluation results of “elongation to hair when wet” in the hair treatment agents of Comparative Examples 1 to 7 are 1 or 2, and “finger when dry” The evaluation result of “Street” is 1 to 3, and the evaluation result of “Relieving effect of the bristle tip” is 1 or 2, and the stretch to the hair when wet, the finger pass when dry, and the bristle tip There were no excellent relaxation effects.
On the other hand, the evaluation result of “Elongation to hair when wet” in the hair treatment agents of Examples 1 to 26 is 4 or 5, and the evaluation result of “Following fingers when dry” is 4 or 5. , "Evaluation effect of fluffiness of hair ends" is 3 or 5, and it is excellent in all the relaxation effects of hair elongation when wet, fingering when dry, and fluffiness of hair tips. The example group had better results than the comparative example group.

  According to the present invention, it is possible to provide a hair treatment agent that has excellent usability, good fingering when dry, and can reduce the crustiness of the hair tips while ensuring the viscosity required for operability and stability. Is done.
